Arsenal made a “very difficult” trip to Napoli “look easy” to seal a 3-0 aggregate win and reach Semifinals of the Europa League.
The Gunners, who arrived at the Stadio San Paolo with a 2-0 lead from the first leg at Emirates Stadium, saw Frenchman Alexandre Lacazette’s first-half free-kick into the top corner earned victory on the night after the hosts had had the better of the early chances.
“We controlled the game really well and defended really well too,” said Cech.
Cech, who is retiring as a player this summer, saved well from Jose Callejon, while Arkadiusz Milik had a goal ruled out for offside – but otherwise the Serie A side struggled to make an impression.
“Napoli are a fantastic team who always score a lot of goals, especially here at home, so to keep two clean sheets is obviously something [positive],” added the 36-year-old Czech.
“It was a very difficult game but we made it look easier because we played really well.”
It ensured a comfortable night’s work for the Gunners as Unai Emery marked his 50th game as their manager.
Aaron Ramsey hobbled off with a suspected hamstring injury.
The Wales midfielder was withdrawn in the first half and will be a doubt for the club’s remaining fixtures before his summer move to Juventus.
Unai Emery has now won 26 matches in the Europa League knockout stages – more than any other manager.
The Gunners will host Valencia in the first leg of their semi-final on Thursday, 2 May (20:00 BST kick-off).
